The Powder Coating Process
The beginning process of powder coating is first making sure that the substrate is properly prepared. The first step in doing this is to sand blast the substrate to get rid of rust and mill scale which causes corrosion. After sand blasting, the substrate is then inspected to make sure all the mill scale and rust is eliminated. Then we move to the next stage of powder coating which is to iron phosphate the substrate.
The iron phosphate serves three purposes; first creates a porous structure that increases the substrate profile. As a result, it improves powder coating adhesion. Second, it provides a barrier of low conductivity that reduces the tendency for corrosion under the powder coating. Third, it creates a chemical bond to the metal surface that helps prevent corrosion from undercutting the powder coating.
After the iron phosphate step is completed the substrate is ready for powder coating. Because the product is going outdoors the best type of powder coating has to be applied. In order to give the product superior exterior protection it has been powder coated with a Zinc Rich Epoxy Primer and then Top coated with a Super durable Polyester Exterior powder with superior resistance against corrosion, ultraviolet rays and chipping.
